IP 265
Operands
• Control system flowchart operands can be placed only in the segments' margin bars.
• The only exception is the connectors, which can also be programmed in the logic field between
COM 265 language elements.
Binary connections
• Binary connections between the language elements can be inverted. Inversion is identified
symbolically by a "squiggle" at the language element's input (at output when connecting line
leads to marginal bar).
• Binary connections between the language elements can be supplemented through the use of
connectors, to achieve structuring of the IP 265 user program.
Connectors
Connectors can be used both in the margin bars and in the logic field of a control system flowchart.
They are used to branch from connections in and between the segments.
• In addition to a # as language symbol, each connector must be assigned a symbolic name (of no
more than 24 characters).
• Connectors can be "written to" only once in the IP 265 user program, but they can be "read" as
often as required and at different locations in the program.
Note
IP 265 connectors can also carry non-binary variables. The data type of the connectors
is always determined by the connection.
Comments
In addition to the segment name, segment comments and operand comments may be input in order
to better document the IP 265 user program. You can program
• A comment for each segment in the IP 265 user program (segment comment)
• A comment for each operand in the control system flowchart (operand comment)
